Chrome扩展程序清单“匹配” [英] Chrome Extension Manifest 'Matches'

问题描述

我正在尝试使用简单的Chrome扩展程序，但遇到了在中为匹配数组提供值的问题。 content_scripts 。

  {
name：My Extension，
version：1.0，
description：我的扩展实验，
browser_action：{
default_icon：icon.png，
 default_title：Ext，
default_popup：popup.html
}，
content_scripts：{
matches：[http：// *]，
js：[scripts.js] 
} 
} 
  

当我尝试将此扩展程序加载到Chrome中时，出现以下消息：
$ b

无法加载扩展程序from'C：\Users\foo\Desktop\Extensions\bar'。
无效的'content_scripts'值。

虽然我看不到什么是无效。我想要做的就是匹配每个URL，所以我的扩展可以操纵任何运行页面的DOM（通过 scripts.js 中的javascript）。我是否错过了一些东西，这些都是错误的，或者是什么？

更新

<在发布这个问题后，我注意到Google的例子与我的例子稍有不同，所以我修改了一下代码以反映它们的语法：

 content_scripts：[{
matches：[http：// *]，
js：[scripts.js] 
} ] 
  

这就是说，我在尝试加载我的扩展时仍然遇到以下错误：

无法从'C：\Users\foo\Desktop\Extensions\bar'加载扩展名。

'content_scripts [0] .matches [0]'的值无效。

解决方案

您需要围绕方括号中 content_scripts 字段的值：

 content_scripts：[{
matches：[http：// *]，
js：[scripts.js] 
}] 
  

（请参阅 Chrome文档了解更多信息）

顺便提一句，使用 http：// * / * 将会更好地匹配所有网址（请参阅文档），并添加 https：// * / * ，如果您还需要匹配这些内容。

在编辑之后，您收到的错误是由于匹配模式不正确。

I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts.

{
  "name": "My Extension",
  "version": "1.0",
  "description": "My Extension Experiment",
  "browser_action": {
    "default_icon": "icon.png",
    "default_title": "Ext",
    "default_popup": "popup.html"
  },
  "content_scripts": {
    "matches": ["http://*"],
    "js": ["scripts.js"]
  }
}

When I try to load this extension into Chrome, I get the following message:

Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.
Invalid value for 'content_scripts'.

I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what?

update

After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax:

"content_scripts": [{
  "matches": ["http://*"],
  "js": ["scripts.js"]
}]

That being said, I still get the following error when trying to load my extension:

Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.
Invalid value for 'content_scripts[0].matches[0]'.

解决方案

You need to surround the value of the content_scripts field in square brackets:

"content_scripts": [ {
  "matches": ["http://*"],
  "js": ["scripts.js"]
} ]

(see the Chrome Docs for more info)

Incidentally, using http://*/* would be a better match for all urls (see the docs), adding https://*/* if you also need to match those as well.

Edit:

Following your edit, the error you are getting is because of the match pattern being incorrect.
